Does anybody know of a database containing minor league stats? Something similar to the Lahman database prefereably. I'm still doing my projections and figured for some of the guys I've yet to do without much major league experience, getting their minor league stats would be helpful.

I know The BaseballCube.com sells them for $40 (they only go back to 2002 anyway) but as usual... I'm looking for something free. If not, I'll just go player-by-player on the Cube but they don't have ratio stats, they just have totals.
